    摘要: The presentation invention relates to methods and apparatus for managing cable network power consumption. An exemplary method in accordance with one embodiment includes the steps of: receiving a message by a cable modem instructing the cable modem to reduce power consumption; increasing, by the cable modem, a buffer size of at least one of: (i) a cable modem downlink buffer included in the cable modem, or (ii) a cable modem uplink buffer included in the cable modem in response to receiving the message; and switching, by the cable modem, from a first mode of operation to a second mode of operation after performing one or both of: (i) transmitting uplink data to the cable modem termination system, and (ii) transmitting downlink data to a wireless base station, said second mode of operation being a power savings modem of operation.

    摘要: The timing of the synchronous interface is controlled by a clock signal driven by a controller. The clock is toggled in order to send a command to a memory device via the interface. If there are no additional commands to be sent via the interface, the controller suspends the clock signal. When the memory device is ready, the memory device drives a signal back to the controller. The timing of this signal is not dependent upon the clock signal. Receipt of this signal by the controller indicates that the memory device is ready and the clock signal should be resumed so that a status of the command can be returned via the interface, or another command issued via the interface.
